[1] Precipitation runoff from the mountain drains north to Knik Arm via Knik River and south to Turnagain Arm via the Twentymile River.

Although modest in elevation, relief is significant as the summit rises approximately 4,400 feet (1,341 m) above the headwaters of Twentymile River in 1.5 miles (2.4 km).

The first ascent of the summit was made March 22, 2014, by Wayne L. Todd and Carrie Wang via the southeast ridge.

The months May through June offer the most favorable weather for climbing or viewing.
